Be it known that I, JOHN rain-innit, a citizen of the United States,residing in North "W ales, Pennsylvania, have invented certainImprovements in Door- Retaining Devices, of which the following is aspeci fication.

The object of my invention is to construct a cheap and efiectiveretainer for holding door in any position to which it is adjusted. Thisobject I attain in the following manner, reference being had to theaccompanying drawing, in which Figure 1, is a front elevation of myimproved door retaining device; Fig. 2, is a longitudinal sectional viewon the line 22, Fig. 1, showing the retainer applied to a door; Fig. 3,is a transverse sectional view on the line 33, Fig. 1; Fig. 4, is adetached perspective view showing the plunger and the retaining pawl;Figs. 5 and 6, are diagram views illustrating the movement of the pawl;and Fig. "I, is a view of modification showing my invention applied as abolt.

A is the casing of my improved door retaining device having a flange aprovided with screw holes a through which pass the retaining screws forsecuring the casing to the door B, shown in Fig. 2. Adapted to thecasing is a shank C of the plunger G offset at c to form a head for thereception of the foot, and projecting downwardly from the head is atubular extension 0 on which is mounted a flexible cushion E, preferablymade of rubber and of sufficient diameter to be forced onto the tubularextension 0. In the tubular extension 0, in the present instance, is acoiled spring 6, which rests against the inner surface of the cushion E,as shown in Fig. 2, so that when the plunger is forced toward the floor00, Fig. 2, considerable pressure can be exerted to force the cushionagainst the floor so as to compress the spring to a certain degree andthus hold the door against any swinging movement after the plungercontacts with the floor.

In order to retain the plunger in any position to which it is set, Iprovide a pawl D, shown clearly in Figs. 2 and 4, which is adapted to arecess 0 in the shank G of the plunger, and in this recess 0 are pivotpins 0 which rest in notches d in the portions (Z Specification ofLetters Patent.

projecting on each side of the body portion of the pawl. The rear edges(Z of these projections are rounded and are made eccentric and restagainst the portions (4 of the casing A on each side of a slot (6Adapted to a socket .c" in the shank G of the plunger is a coiled spring7' which bears against the upper surface of the pawl D and tends toforce it down, rocking it on the pivot 0 llhen the pawl is in theposition shown in Fig. 5, the rear portion (Z rests against the surfacea of the casing, the pawl being forced down by the spring f, causing itto rock on the pivotsc. Thus any tendency to force the plunger up so asto raise it ofi the floor is prevented by the jamming of the pawlbetween the plunger and the casing, but by simply pressing the footagainst the underside of the projectin portion (Z of the pawl, shown bythe arrow, Fig. 6, the movement will compress the spring f and throw thepawl out of engagement with the portion a of the casing, releasing theplunger, which can be elevated to any position desired by continuing thepressure on the underside of the pawl D, the pawl carrying with it theplunger until the plunger is clear of the floor, then the door can beopened or closed, or adjusted to any position desired. 13y pressing thefoot on the portion 0 of the plunger the plunger can be forced down incontact with the floor and the resistance can be increased by applyingadditional pressure upon the plunger, compressing the spring a andlocking the door against movement in either direction.

My improved door retaining device can be made of any suitable material,or may be of any size, depending upon the character and size of the doorto be retained.

In some instances the cushion E may be dispensed with and the ends ofthe plunger made solid, as shown in Fig. 7, and adapted to a cavity sothat it will have the same function as a bolt, retaining the door orother device rigidly in position.

I claim l. The combination of a casing, a plunger mounted in the casing,an eccentric pawl pivoted to the plunger and adapted to bear against thecasing, a spring for forcing the pawl against the casing, whereby theplunger will be retained against end pres sure in one direction by theeccentric pawl bearing against the casing, but .will be free to move 111the opposlte d1rect1on when the pawl is shifted soias to clear thecasing.
